DOI: 10.1002/tcr.202300038
Abstract: Interaction of enol ethers enol acetates, enamides and enamines with fluorinated reagents may be considered as a reliable method for the synthesis of organofluorine compounds. While classic nucleophile/electrophile substitution or addition mechanisms cannot be realized… read more here.

DOI: 10.1021/acs.orglett.0c01395
Abstract: The base-induced reaction of aryl diazonium salts with commercially available CF3SO2Na/CF2HSO2Na allows for the generation of the corresponding diazene radicals along with fluoromethyl radicals. The addition of fluoromethyl radicals to alkenes with subsequent diazene trapping… read more here.

DOI: 10.1039/c7qo01138e
Abstract: We report the first allylic isomerization of alcohols catalyzed by nBu4NOTf generated in situ from tetrabutylammonium triflate and potassium tert-butoxide. Substituted ketones could be prepared under mild conditions in good to excellent yields. The relationship… read more here.

DOI: 10.1039/d3ra02247a
Abstract: The selective and controllable construction of spio-tricyclic skeletons through visible light promoted radical cyclization still remains challenging. Herein, a general and convenient protocol for the blue light-promoted radical-mediated cascade spiro-cyclization/Michael addition of N-arylpropiolamides with thiophenols… read more here.
